What survives of the wall that once ringed Roman Barcino, and the oldest visible thing in Barcelona. There is no entrance and no ticket: the preserved stretches are built into the fabric of the Gothic Quarter and you walk past them in the street. The clearest section is at Plaça de Ramon Berenguer el Gran, where Roman towers rise and the wall of the medieval royal palace sits directly on top of them. That stacking is the whole point: two thousand years of building on itself in a single elevation. Other fragments turn up in corners around the quarter, some inside private buildings, some in museum basements. Anyone wanting the full sequence will find it at the city history museum, where you can descend to the Roman streets underground. This is not a visit in the sense of a ticket and a route. It is a layer you notice while walking. Give it half an hour inside a Gothic Quarter wander rather than treating it as a separate sight.

No entrance, no route: the remains are embedded in the streets and you notice them in passing.
The city history museum takes you down to the Roman streets of Barcino for the full picture.

Not to see the stones, but context makes the difference here, because without explanation it reads as an old wall. Information panels exist, and the city history museum lays out the sequence far more clearly.
